Sailors Ahoy! Moomin Sailors is a collection with a nautical white and blue colour theme spiced with some lovely Moomin details. Tove Jansson loved the sea – and that is why sea has such an important role in her Moomin stories and illustrations. Muurla’s enamelware consists of a carbon steel core that carries a double-coating of enamel. Enamel jar is dishwasher safe.  The lid of the jar is made of natural cork and it’s not dishwasher safe, so handwash only.
